Technics SL1200/1210 owners - which mat?

I've upgraded to the Boston Audio mat, it's quite a big improvement over the stock rubber mat. I thought the stock rubber mat sounded very loose and ripe in the bass. The mids and highs were drowned out by the loose bass. Maybe this is the 'dark' sound people are referring to when listening to the Technics?

The Boston Audio Design Mat1 brings the sound together, firming up the bass, and bringing it in line with the mids and highs. Far more cohesive presentation.

What other mats have you tried and are using?
